East Side Villages Wastewater Phases 1, 2 and 4, 5
We were contracted for Phase 1 of the East Side Villages Wastewater project, and subsequently awarded Phases 2, 4, and 5.
Phase 1 involved the rehabilitation of Clarigester No. 1, upgrades to the influent pump station, and chlorine contact chamber piping modifications at the Utulei Wastewater Treatment Plant.
Phases 2 and 4 involved the construction of the 20” Ø sewer force rising main from Malaloa to Utulei, and the construction of the 12” Ø sewer force main from Malaloa to Leloaloa. The project was split into two packages (2 and 4) which were awarded as a combined package.
Phase 5 involved three new sewerage lift stations; force mains and lateral sewers; service connections to existing facilities and decommissioning of existing septic tanks and cesspits; and new sewer manholes, concrete works, metal works, and electrical work.
Highlights of the project included successfully excavating around an abundance of existing services, both known and unknown, and the successful completion of the Horizontal Directional Drill under the river. Significant effort was put into training local employees in the specifications and skills required, leading to a more capable and resilient workforce.
